- Increased APIVERSION (forgot to do that in 1.5.2 and 1.5.3). - Fixed a crash in i18n character set conversion (thanks to Alexander Riedel, Jose Alberto Reguero and Christian Wieninger for patches that cured part of the problem). - Adjusted the 'skincurses' plugin to UTF-8 handling. - Using nl_langinfo(CODESET) to determine the local codeset to use (thanks to Thomas Günther). The codeset names in 'libsi/si.c' have been changed to the canonical spelling with '-' (thanks to Ludwig Nussel for pointing this out). - Modified handling invalid characters in VFAT mode. - Replaced strn0cpy() with Utf8Strn0Cpy() where necessary. - Now using 'fontconfig' to determine which fonts to use (thanks to Anssi Hannula for code and hints on how to do this). - If no fonts are installed, VDR now uses a dummy font that doesn't actually draw any text, and logs an error message. - The new function cFont::CreateFont() can be used by plugins to create and use fonts of their own, independent of VDR's standard fonts. - Updated the Finnish OSD texts (thanks to Rolf Ahrenberg). - Changed the parameter "OSD font" to "Default font" in "Setup/OSD" (suggested by Rolf Ahrenberg). - Fixed handling detached processes in SystemExec() (thanks to Udo Richter). - The info.vdr file now also stores the name of the channel, and the new function cRecordingInfo::ChannelName() returns this information if available (based on a patch from Alexander Hans). - The new function cOsd::SetOsdPosition() can be used to dynamically change the position and size of the OSD (based on a request from Christoph Haubrich). Plugins that implement skins should no longer use Setup.OSDWidth etc. directly, but should rather use cOsd::OsdWidth() etc. instead. Currently a change to the OSD position will only apply to newly opened OSDs.
